In large organisations, the department will be having many break ups. Like HR Department, having Leave, Promotion, Personal Documentation, Discipline, Welfare, like that so many branches will be there. Normally Mr. A will be deployed as main for Leave and Mr. B will be in training, Mr. B will be main for Promotion and Mr.C will be in training, Mr. C will be Main in Personal Documentation and Mr.D will be in training, Mr.D will be main in Discipline and Mr. E will be under training, Mr. E will be main in Welfare and Mr. A will be under training, for first three months and it will be rotated branchwise, so that if a person left the organisation or on long leave, the regular work will not get hampered. That's the purpose of job rotation, which is not at having any relation with cadre or promotion. Here all the employees can learn all the job in the department.
The advantages of this system is that no work will be hampered due to non availability of manpower. The bore feeling will not be there to any employees because of repetition of work. This will lead that the employees also will be deployed independantly in any new offices to have control over the entire department. The Idle manpower can be utilised properly and wherever the workload is more the extra manpower deploying will not be much problem as the entire team has been trained in the same way by further rotating them on monthly basis or quarterly basis.
